Terengganu formerly spelled Trengganu or Tringganu, is a sultanate and constitutive state of federal Malaysia. The state is also known by its Arabic honorific, Dāru l-Īmān (“Abode of Faith”). The coastal city of Kuala Terengganu which stands at the mouth of the broad Terengganu River is both the state and royal capital as well as the largest city in Terengganu. There are many islands located close to the coast of Terengganu state, such as Redang Island.
There are several theories on the origin of the name “Terengganu”. One theory attributes the name’s origin to terang ganu, Malay for ‘bright rainbow’. Another story, said to have been originally narrated by the ninth Sultan of Terengganu, Baginda Omar, tells of a party of hunters from Pahang roving and hunting in the area of what is now southern Terengganu. One of the hunters spotted a big animal fang lying on the ground. A fellow party member asked to which animal did the fang belong. The hunter, not knowing which animal, simply answered taring anu (Malay: ‘fang of something’). The party later returned to Pahang with a rich hoard of game, fur and sandalwood, which impressed their neighbours. They asked the hunters where did they source their riches, to which they replied, from the land of taring anu, which later evolved into Terengganu.Terengganu was called Trangkanu by the Siamese when it was under their influence. Terengganuans usually pronounce Terengganu as Tranung or Ganu.
